Patented Nov. 22,- 1932 UNITED STATES PATENT OFFICE JULIUS a. wnmmnoaa, or NEW YORK, N. snnn'r rILme Application filed November 21, 1930. Serial No. 497,319.

This invention relates to sheet metal piling and more particularly to corrugated sheet metal piling of the type covered by my Patent No. 1,166,563, dated January 4, 1916, and consists in the improvement hereinafter described and illustrated in the drawing, in which; i Fig. 1 is a cross-sectional view of one pile and of the edges of two adjoining piles;

Fig. 2 is a front elevation of one of the piles; and

Fig. 3 isa detail sectional view of a modification.

The advantages of this type of piling are fullyset forth in mysaid patent. It comprises interlocking meanswhich enables the piles to be interlocked by lateral movement as distinguished from the longitudinal driving of one pile into engagement with another, alread in situ. The interlockingmeans of the pi ing, disclosed in my said patent, consists of cli s riveted or otherwise secured near one of the mar inal edges of each pile and so shaped as to cave a space between it and the marginal corrugation to' receive the edge of the marginal corrugation of the adjoining pile. The riveting on of these clips in the required positions considerably increases the cost of the piling.

It is the object of the present invention to I providing and ateliminate the extra cost of taching these clips and at the same time, to reduce the weight of the piles.

I obtain these desirable results by forming the clips out of the metalof the piling itself, by punching them up in suitable dies.

The piling illustrated in the drawing is by wa of example only, since it is obvious that t e invention is equally applicable to other forms of corrugated sheet piling than that shown, in which the corrugations are semi-circular without the intermediate tangents shown in my patent aforesaid.

Referring now to the drawing, 1 are the main or body corrugations of the sheet and 2, 3, the marginal ones. The outside radius of the corrugation '2 is equal to the inside radius of the corrugation 3, so that the edge of one pile fitssnu ly in the edge of the adjoining pile. As s own, the corrugations 2 and 3 are of lesser radii than the body corrugations 1, the purpose of which is set forth in my said patent, but this construction'has no bearing on the present invention. The clips comprise the curved ends 4 of small radius-and the shanks 5, joining said ends to the body of the ile.

It sometimes appens that the clips become bent in the handlin of the piling and, to prevent this, I may orm strengthening ribs 6 on their backs -in the operation of punching them out and die-shaping them.

The plates described are useful for other purposes than piling, for example, as a metal base in road construction.

Having thus described my invention, what I claim is:

Corrugated sheetpiling having interlocking clips punched out of the corrugation next to. one of the marginal corrugations.
